Microsoft SQL Server 2014 KB3162659 – Error 0x80070643

While we normally focus on Consumer products of Microsoft this time we want to make an exception since the amount of questions regarding the error code 0x80070643 while updating Microsoft SQL server is rising immensely on the web.

In this article we will discuss a method that worked for some, so it might not help you but it’s worth the shot. We suggest you make a backup of each database you have running on the systems affected by this issue.

Method 1: Repairing .Net Framework

Make sure that your booting Windows clean, to prevent other services from interfering with Windows Update. If you did not yet setup clean booting, then read this article and reboot after completing the article.

After Windows has rebooted start Windows update again and apply all updates including KB3162659.

Microsoft SQL Server 2014 SP1 Update KB3162659 should now be installed without any errors (0x80070643) like you received before. We are currently looking for more methods which seem to work for some people. If method 1 did not help you then feel free to visit our forums and ask there for help in fixing this issue.
